Mobile market brings affordable groceries to food deserts
NCT ID NCT05672186
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether a full-service mobile market that sells affordable groceries (about 10% cheaper than stores) can improve diet quality and reduce food insecurity in low-income neighborhoods. Researchers enrolled 262 participants from 12 community sites, randomly assigning some to get the market weekly and others to a waitlist. They measured diet through phone interviews and tracked food purchases over 6 months.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Full-service mobile food market offering affordable groceries
- What this could lead to
- If successful, this could show that mobile markets are a practical way to improve diet quality and reduce food insecurity in underserved communities.
- What could go wrong
- This is a completed study, but results may not apply to all communities. The study is relatively small (262 participants) and focused on specific low-income sites, so broader impact is uncertain.
